The sameperoidlastyear function calculates the value for its year and not the previous year

[Anonymous]

Hi,

I'm having trouble writing a measure that calculates last year's value. Below is an image showing what I mean:

I need the "Wolumen YA" measure to calculate growth in the current year relative to last year. For reasons I don't understand, the measure calculates the value for its year. Below is the measure:

Wolumen YA = CALCULATE([Wolumen], SAMEPERIODLASTYEAR(Dates[Date]))

Maybe someone has encountered a similar problem and will be able to explain what's wrong here.

Hi @Anonymous 

Thanks for the reply from Greg_Deckler and HotChilli .

@Anonymous , the following test is for your reference.

My sample:

Create several measures as follow

This year = SUM('Table'[Value])

The measure was created just to restore your scenario, as I don't know the creation logic of your Wolumen.

Measure = 
VAR _year = MAX([Year])
VAR _month = MAX([Month])
RETURN
CALCULATE([This year], FILTER(ALL('Table'), [Year] = _year - 1 && [Month] = _month))

Measure 1 = SUMX(VALUES('Table'[Month]), [Measure])

Last year = SUMX(VALUES('Table'[Year]), [Measure 1])

Output:

What's in the matrix visual? Which tables are used in the model? What are the relationships?

What is the measure [Wolumen]?
